120 Million Buildings in the USA
US Buildings is an interactive map of all 120 million buildings in the USA. The map uses data recently released by Microsoft to visualize 124,885,597 computer generated building footprints.
The building footprints were generated by training computer vision algorithms to recognize building geometries on aerial imagery of the USA. OpenStreetMap currently shows 30 million building footprints in the USA so Microsoft's USBuildingsFootprints is a significant increase. The data is free to download under an Open Data Commons Open Database License.
For this interactive map the data was loaded into QGIS and rendered as monochrome tiles with the QTiles plugin. The map tiles don't have a high enough resolution level to observe individual footprints. It does however provide an interesting accompaniment to a population density map of the USA.
